Products Description
Degassing Equipment:
The degassing of aluminum is based on the principle that dissolved hydrogen gas will move from an area of high concentration (in the melt) to an area of low concentration (in the inert gas). Hydrogen gas disperses in molten metal as it would if it were released in any confined space. It will maintain a constant concentration throughout the melt. Hydrogen gas can migrate in liquid metal almost as fast as it can in air. Therefore, it is unnecessary to bring every ounce of metal in contact with the inert gas.The efficiency of aluminum degassing is determined by two factors, the transfer rate across the metal/gas interface and the total surface area available for transfer.
Working Priciple
The working principle of online refining of molten aluminum using rotating nozzles one or more rotating nozzles shear the process gas (usually argon) into small bubbles throughout the smelting process. Hydrogen rises with the process gas bubbles and is released from the molten aluminum。
At the same time, during the floating process of the inert gas, due to the effect of the surface tension of the air flotation, the inclusions in the molten aluminum will be adsorbed on the surface of the bubbles and taken out of the molten aluminum to achieve the removal of inclusions nclusions can be removed from the system by normal skimming operations.
According to the actual use of the user,
the passing flow rate per hour and the required hydrogen removal effect, the residence time required for the aluminum melt will vary. According to this situation, we design the efficiency of degassing to be the volume of the inner cavity.

Special structure: box body seal
The sealing structure of AdTech degassing equipment is based on the sealing method of vacuum degassing equipment. The sealing between the box and the box cover, the sealing of the inlet and outlet flow grooves, the sealing of the rotor heater protective cover and the box cover are fully carried out. The sealing design can effectively prevent the slag formation caused by the secondary oxidation of the aluminum melt, and effectively improve the degassing effect.

Degassing Control cabinet
AdTech's degassing device can use argon and nitrogen; (as an option: it can be designed to use argon +chlorine gas mixture safely. It is a device with excellent anti-corrosion structure, this project does not contain chlorine gas device, so I won't go intodetails. introduce.)The gas control cabinet is equipped with process gas, backup other and backup power, protective gas and cover gas pipelines , each pipeline is equipped with pressure and flow adjustment devices, when the refining gas pressure is abnormal, an alarm is output, and when a power failure occurs and When the gas flow is insufficient, the gas can be automatically switched to prevent rotor blockage and degassing failures. There are two modes of protective gas: manual/automatic. When the molten aluminum is stored or preheated, the protective gas is turned on to enter the protective mode, and the protective gas is automatically turned off in the oven mode.
Degassing Rotor
The degassing rotor assembly is composed of a rotating nozzle and a rotating shaft made of silicon nitride. It has the characteristics of high strength, long service life and low maintenance intensity. Its special structure produces better bubble dispersion, which can improve and increase bubble trapping. The probability of hydrogen and impurities, while avoiding the generation of vortex on the melt surface, so as to achieve the effect of efficient degassing, slag removal and alkali metal
removal .The degassing rotor is directly driven by the motor, and the inverter can be controlled to rotate at any speed between
0-600rpm to meet the requirements of the production process.

Our Advantage:
1. High degassing efficiency, the average degassing efficiency is above 65%. It is not inferior to the degassing efficiency of fully imported equipment.
2. The sealing effect is good, and the sealing method of vacuum degassing is adopted, and the sealing of the entire box body and the box cover, the sealing of the rotor and the heater protection sleeve and the box cover is the best.
3. Good thermal insulation performance, the thermal insulation layer adopts the thermal insulation design after temperature field simulation, 3 layers of nanofiber boards are combined with other thermal insulation boards, and the shell temperature is below 65 degrees.
4. Good stability. Through the structure design of the box and the matching of the corresponding ventilation volume and the rotor speed, it is ensured that the molten aluminum enters the box and is always subject to degassing; Gas efficiency is high and stable.
5. The material of the box has a long service life, and the inner lining of the box is relatively critical. Our company has
developed materials suitable for high-purity aluminum to avoid the pollution of the aluminum liquid. Moreover, the lining material of the box is resistant to corrosion and has a long service life. The market feedback has an average service life. over 3 years.
6. Professional in after-sales technology. The company specializes in the production and development of aluminum melt purification materials and equipment. It is more professional in the application of equipment on site, and can design according to customer site conditions to ensure more convenient and reasonable operation.
